(a), (b) Two-dimensional and (c), (d) three-dimensional representations of the anglar wave function for a staten_l= 4. In panels (a) and (b),Q(θ) = 1.57638(1.5865 + 16.793(−1 + cos(θ)) + 42.105(−1 + cos(θ))²+ 36.695(−1 + cos(θ))³+ 10.215(−1 + cos(θ))⁴)²(1−cos(θ))^0.2(1 + cos(θ))^1.16; in panels (c) and (d), (θ) = 1.57638(6.7983 + 39.2793(−1 + cos(θ)) + 67.9901(−1 + cos(θ))²+ 45.3199(−1 + cos(θ))³+ 10.2495(−1 + cos(θ))⁴)²(1−cos(θ))^1.4(1 + cos(θ))^0.27.
